I'll put it to you this way.
This is not a "Game Tycoon" game
Game development is of tertiary importance in the game. So if you are getting it for that reason, look away.
Basically how it works is you chose to develop a game and then you need to get all the software and licenses to develop for including the platform.
Then you (well you can do it in any order) select from a list of features and these modify how good your game can "potentially" be. These might increase the 'recommended team size' (which arbitrarily slows down production, you get a penalty for not having the right size) so make sure you have enough people. After you select enough "Features" to make the game as good as you want it you send it to production.
You can also market your product (it doesn't have to be a game at all) and when you do you get bonuses to its total profit.
Development depends on the skill of your team. The higher their skill the faster it goes and the more they avoid "Delays" (which think of it like an engine stalling). When the development phase is at a "quality" you are happy with you can send it to Beta and then Alpha (Some projects don't get Betas)... THEN bug squash.
THEN after it is released you can market it to take its money. Essentially it has a potential earning and you want to eat up the cash.
I would probably say... unfortunately... that
Game Dev Tycoon is definitely the better game by a vast margin.
Sure there isn't as much "depth" but Game Dev Tycoon has a ocean of "Point" compared to this one... You feel like you are actually making a game in Game Dev Tycoon and while you can still just add features, the features still have to interact with the game you are making.
That is, if you are still thinking of this as a Game Tycoon game.
In fact this Title for this "Game Dev Tycoon + Sims" is probably the biggest lie of all... in that it is a flat out lie on both accounts.
This isn't a game about developing games, you just happen to be able to develop a game, and this isn't a game about the interpersonal interactions between people.
This game is closer to "Capitalism" IMO, the game where you make factories and sell the product.
I can't in all honesty even call this game bad... I just know that it doesn't scratch that game development tycoon itch.
I mean half the game is just trying to build a location to maximize the efficiency of your team and keep yourselves from slowing down. You don't even need to keep track of market trends because the game does it for you (no really! It will outright tell you how "innovative" you are being)
